This invention relates to containers for pulverulent or granulated substances such as powdered soap, face and talcum powders, tooth-powders, pharmaceutical products, etc.

5 'Theinvention and its aimsand objects will be best understood from the following description, taken in conjunction with the accompanying drawings of an embodiment thereof herein describedand shown for illus- *trative purposes,the true scope ofr'the inven-' tion being more particularly pointed out in Fig. 6 is across section'of thecontainer near its upper part showing the foraminous closure andmeans to restrictrelative movement of the walls of the container;

Fig. 7 is a cross-section of the same con-' tainer showing the means for restricting rela- 3G tive movement of the walls of the container,

the latter being in collapsed position;

Fig. 10 is a longitudinal section of the containershown in Fig. 9; i Fig. 11 is a perspective view of the container tapered toward its discharge opening;

Fig. 12 is a cross-section of the upper part ofthe casing, such as shownin Fig. 6 illustrating means for agitating the powdered contents, thus preventing caking and furthering the discharge of the contents mm the container;

Fig. 13 is a detail of the means shown in Fig. 12, inclosed position of the container; Figs. 14 and15 are views of the parts for container is distended by pressure on the opthesame purpose as those in Figs.'12 and 13,

respectively. The container proper 1 may be made of any suitable material, cardboard, thin metal, celluloid, composition, leather, fabric, etc. It

may be of any suitable shape, the preferred shape herein being substantially that of a lozenge in cross section when the container is distended, and substantially wedge-shaped in longitudinal section. The container will 7.

preferably be provided with means permitting distension thereof, said means herein comprising plates forming reentranting angles at 3 along its opposite sides and obtuse angles at 4 along its top and bottom.

The plates at 3 will preferably be formed'to permita larger separation than the plates permit at 4 so as toincrease the capacity of the container byiproviding increased separation between its top and bottom walls. It

will be apparent that pressure exerted upon the opposite side edges 3 of the container cause the latter'to be distended in the form of alozenge. The walls 1 are connected at their lower ends by a flap joint 2.

The open end of thecontainer willpreferably be closed by a closure 5 or 7 placed in position after the container has been filled.

This closure may be solid, in which case it will preferably be made of paper, gelatine, cellophane, gold-beatersskin, fabric, or any other suitablematerial of a breaking strength sufliciently low to rupture readily when the posite edges 3.

Instead of a solid closure a partial closure '7 may be provided "formed by a sheet of foraminous material, for example relatively closely woven fabric, fine net, flexiblemetallic netting, or the like. The foraminous closure is stretched overfthe open end of'the container when the latter is distended, so that it per- ,mits and follows the contractile and distend ing movementsofthe container producedby pressure on the opposite edges 3; these move ments of the fora-minous closure facilitate the pevacuation of the powdered contents of the container therethrough. The container may cessive pressures exerted upon the opposite edges 3 of the container alternately to distend and contract the same will cause the material to pass through the closure into the container.

In Fig. 3 the flap joint 2 of Fig. 2 is replaced by a supple joint 15 which enables the bottom of the container to be extended and increases the capacity of the container. The sheath or case 8 is so fashioned at its lower end 9 as to enable the flexible joint 15 to be extended without protruding from the case. The opening of the case at the discharge end of the container will be preferably closed by a cover or flap. 10 which, in closed position, overlies a flange or lip 11 surrounding the discharge end of the container, said closure-flap 10 being secured in closed position by any suitable means such as a snap fastener 12 -14 for example.

The lip 11 prevents the contents of the con tainer from being spilled when the container is returned to uprightposition after use, it also permits the amount of powdered material to be introduced into the container to be placed on the foraminous closure. The lip 13 of the fastener facilitates the opening of the latter and it will thus be noted that the casing may be opened, the container used and the easing closed again with one hand.

Figs.'9 and 11" show containers having a relatively small discharge opening closed by a closure 5. As will be seen the container of I Fig.9 is tapered at 30 upon one side While the container shown in- Fig. 11 is tapered at 33, 33 upon two sides. The container of Fig. 11

may be provided with a paper cover, as shown in Fig. 10, at 31 and 32.

The smaller discharge opening of these containers is advantageous in filling receptacles having a relatively small opening, such as the powder-puff holders of pocket vanity cases.

Means are provided in accordance with the invention for restricting the relative movement of the walls of the container, and for agitating the contents upon relative movement of the walls of the container, thus preventing caking and furthering the discharge of the contents from the container. Such means may be of any suitable construction in accordance with the invention. Referring to Fig. 1, convenient means for this purpose may consist of wedges 6 secured to opposite walls of the container within the latter; In Figs.

6 and 7 said means as shown, conveniently comprise spring members16 and 18 secured in any suitable manner adjacent their ends to the opposite walls of the container, as by rivets' 22, 23 and 20, 21, respectively. Said members are provided with bosses 17 and 19, respectively. These bosses, like the wedges 6 'in Fig. 1, limit movement of the walls of the container'toward each other when the container is collapsed and the spring members tend to restore the container to a collapsed sure on the edges 3. Both the wedges 6 and spring members agitate the contents of the container as and for the purpose above referred to. In Fig. 8 the spring members of Figs. 6 and 7 are replaced by an elastic band 24 secured at one end 25 to the inside of one wall of the container and at its other end 28 to the inside of the other wall of the container, said band passing through eyelets 26 and 27 secured to the inside of edges 3.

In Figs. 12 and 13, a convenient embodiment of means is shown for agitating the contents of the container. Said means herein comprises two blades 35 and 41, the blade 35 being secured by its reversed end 36 to one wall of the container adjacent its edge and the blade 41 being secured to the opposite wall of the container adjacent its opposite edge by its reversed portion 42. The blade-35 is provided with a boss 37 on the side toward the blade 41 and is adapted to slide in a guide 44 carried by the blade 41. Similarly the blade 41 is provided with a boss 43 on its side toward the blade 35 and is adapted to slide in a guide 38 carried by the blade 35. The blade 35 carries an extension 40 hinged thereto at 39 and the blade 41 carries an extension 46 hinged thereto at 45. From the above description it will be apparent that when the container is distended by pressure upon its opposite edges 3, the blades 35 and 41 will slide inwardly relative to each other and their hinged extremities 40' and 46 meeting bosses 43 and 37, respectively, will be swung in opposite directions away from said blades, thus agitating the contents of the container. When the container is allowed to collapse the bands and swinging end portions return to normal position.

In Figs. 14 and 15, similar means are provided, said means therein conveniently comprising two spring bands 47 and 51 secured by their reversed end portions 48 and 52 to opposite walls of the container adjacent the edges 3 of the latter. Said bands 47 and 51 are riveted the one to the other at 50 and 54 and the band 47 is hinged at 49 while the band 51 is hinged at 53. It will be apparent that if the container be distended by presare preferably placed adjacent the discharge end thereof and closure, particularly the forami'nous closure where their operation will be most effective. I

I am aware that my invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiments to be considered in all respects as illustrative and not restrictive, reference being had to the appended'claims rather than to the foregoing description to indicate the scope of the invention.
